Quick question, have a p3 fat no hdmi but works when using av kabel. Was it the chip that was causing the issue or a filter cap?

@@momfiethehunter504 would like that answer since yesterday i lose my hdmi output too ('experimented' with hdmi cables too much)

What does the encoder serve for?

What school lmaoo your in it's called KZfaq university lol. So what is a degree gonna do? Take it with you every repair? Better off getting a certification save your money brother. You dnt need a degree to prove to yourself your a tech.

O don't think but if it has Surely a factory machine ,it's not like any other multimeter ,

Excellent info mate many thanks :)

Coming across some of your and Mr. Paul's posts, and this is super helpful. I'm trying to track down the P/N for the PS4 4-pin filters as well, but this is great info. Thanks!

PS4 EMI Filter (10xx/11xx/12xx) - DLW21SN900HQ2L PS4 EMI Filter (Slim/Pro) - DLP11SA900HL2L

@@AndrewPaul Thank you, Andrew! Your channel has been incredibly helpful over the years!

Thank you :-)

Cheers mate - as you say hopefully it won't be long before they start coming down some more and like you I've found they're all pulls too regardless of what the listings might otherwise say. :(

Many thanks.

Hi, Yes I only use new MN864729 - lifted QFNs you can never be sure of the longevity as these are fairly weak components at the best of times. If I were you I'd use a good quality flux like Amtech NC-559-V2-TF, run a bead around the edge of the QFN and with a sufficiently powerful iron and good sized tip run a bead of quality leaded solder around the pads. They should take it up and it'll make it much easier to solder to the board with hot air after that.

Hi Pascal, The trick is to hold the IC in place with tweezers until the solder flows beneath. Heat the solder and pads on the motherboard prior to offering up the IC to minimise the amount of heat you apply to the IC and the amount of time you need to hold the IC steady while the solder flows to attach the IC. Once it's attached to the large ground pad in the centre then the airflow won't blow the IC from the board. Once the chip is attached to the board, add flux and let surface tension do the work to pull the IC into its final position. A quick push down at the end of the cycle to ensure each pad is in contact and you're done :-)

Thank you for response and keep up with the good u should be an example for the whole community. Cheers

Many thanks :-)

Cheers mate.

Andrew Paul nice

You could but it's not imperative. Remember these things are installed during production with lead-free solder and are designed to withstand the required temperatures. It's only due to inefficient or incorrect installation techniques when the temperatures involved go beyond tolerance and will then damage the IC.

Can't say that I have - heard from a couple of sources that one or two earlier consoles this did work for however I just get them swapped out as probability is that the chip is toast.

@@AndrewPaul thank you!

Many thanks.

Thank you.

Many thanks.

Hi, Any in particular?

Have you checked the EMI filters for continuity? Also, do you have any means of microscopic inspection equipment to check the landing of the QFN? By eye it can look fine but you can only really see if it's properly soldered with some serious magnification.

yes i forgot to say i checked all the emi filters and they are all good. yes i have a microscope so i double checked all pins are ok on the encoder ic. have you ever worked on any SAC-002 versions as the hdmi pinouts are diffrent on this version. and theres no local diodes nearbye the hdmi port apart from one on the left side from pin 1.. so not sure what other diodes or resistors on the hdmi curcuit to check. as theres no schematics for these, and i dont have a donor board to compare.

It's in the vid - 485C @ 100l/min.

Andrew Paul gracias

+David Woollard 490C @ 100l/minute.

490C @ 100l/min

Mira la resistencia que esta en uno de los diodos de protección tiene que ser de 22 ohms, a veces se corta y por eso no da imagen por hdmi.

To be honest you can either take them from a defunct board, PS3 motherboard or if all else fails bridge a wire - all will do the same job but I'd recommend replacing it rather than bridging it at least long-term. I'm not sure of a part number - without schematics it's pretty hard to say.

thanks for the quick answer, i will try to bridge them first, if it works i will see where i can get a replacement for the filter or coil. i came along an article where someone used a smd 0805 90 ohm at 100 Hz 0,28 Amp filter next to each other. Thanks again

sometimes I add some low melt solder paste to bring the melting temp of the no lead solder down. I then have to clean all the solder off and apply new solder, but sometimes its easier to do that anyways.

Hi, if the connector looks fine then I'd replace the IC. Sound artifacts are usually indicative of an IC failure.

In the meanwhile, before I red your answer, I replaced the hdmi connector, but that wasn't the problem. Tomorrow I will replace the hdmi IC.

Replaced hdmi ic and everything is working again. Had to clean the hdmi connector, because flux went to the pins. A toothbrush, pressed air and IPA, did wonders. I have a great idea, what about designing a PCB, which will be connected to the input lines of the HDMI part, which will solve every WLOD, no matter how much the hdmi part has been damaged. Should that be possible ? That should also be possible with Blayray drives, for which the controller board part, is on the mobo. Of course we need to move the Renesas chip to the controller board. Need to go into dept in my Basic Electronics book, to understand everything. I am a mechanical engineer, not an electronical engineer.....

It's flux paste - Amtech NC559-V2-TF to be precise. Any Panasonic MN864729 will do.

If you have shorts left-to-right across the filters then the likelihood is that the IC is defective. To test, remove the affected filter and retest it off the board. If the short disappears, but is still present on the now vacant pads on the PS4 motherboard then the IC itself is faulty and must be changed.

Andrew Paul thanks you my PS4 is not show signal n hdmi seem like it ok

Hi I do PS4 repairs model is SAC001 power supply is good 5 volt and 12 v is good but in the main it won't turn on can you tell me why

Hi, It's likely to be a short across the differential pairing within the Encoder IC. If you remove the encoder IC, I bet you'll find the short in the EMI filter will suddenly disappear. If it does, replace the IC with a new part. The filters from an SAA/SAB revision board work fine on the SAC so you should be fine with those in place.

Andrew Paul ok i will try this, thanks a lot for your info! I will let you know when I try it! Grtz from Belgium

Hello andrew! As you said after removing the hdmi chip the filter didnt crosscontact. After placing an other hdmi chip, i started the ps4 but i only got a blue screen with black lines and no sound at all... i assume this hdmi chip is also broke?

Very possibly so - either that or a shorted pair of pads around the IC somewhere. There's some life there though so it's progress ha ha! :)

Andrew Paul enough working for today, tomorrow im gonna try to do it again, if nothing i will have to order another chip! Thanks again for your support and video's with a lot of info!!! Keep up the good work!!!

My scope is an Amscope SM-4TPZFRL. It comes with a 3MP USB camera however I have since upgraded to a HDMI camera as an aftermarket upgrade which can be seen in this video - the capture device it's plugged into and KZfaq encoding doesn't do the image quality justice sadly. Price to the UK by the time shipping and customs charges are accounted for were just over £850 and would probably be pushing past that now to approx £1k with the GBP to USD exchange rate being as weak as it is. However, it is a very highly recommended piece of kit.

Hi, The second number is just a batch / serial and doesn't matter. As long as it's an MN864729 it'll work fine.

Andrew Paul that’s great thankyou.

EMI Filters should be checked for continuity on the 1200.

They are all good :(

Rework station setting is 485C @ 100l/min. Lead-free solder will melt @ 217C but you'll need the additional heat and high airflow to heatsoak the board to be able to lift the IC easily and without damage to the motherboard.

ok thank you

Yes - the board in this video is from a 1215.

It's on the video bud - 485c @ 100l/min.

very thanks buddy

Station is a Quick 861DW.

awesome. thank you

You can contact me at brettsiphonerepair@gmail.com

Wait nevermind im in america can't send it to you

+Brett Peterson sadly for what they're worth the shipping makes it uneconomical.

Is this only in game? Do you have any pictures of the issues at all?

hi good morning andrew i can send you a small video you will see better the fault

Sure - if you upload it and post the link it should give a good idea as to the issue.

thank you very much adrew for your great help when I got home I sent the little video

hello andrew this is the video where the image of the ps4 with stripes as interferences comes out, sorry for not speaking in the video, we do not speak english, many thanks for your help

Maybe the problem are in the four filters between IC and HDMI port.

na, all good as like in the video. i'll buy another one from reputable seller to try again. yes these ic are expensive.

Forgot to mention, its a CUH-1115A model.

Are the EMI filters intact? Also, have you replaced the encoder with a known-good part to rule that possibility out?

Yes, the filters were good. I tested the continuity through them as you did in this video. Havent replaced the encoder IC yet, but I did resolder the legs. I'll replace encoder today when it gets delivered and report back if it worked.

Thanks for your help Andrew. Just wanted to report back that when I went to replace the encoder I took one last look at the pins and realized that there was indeed the tiniest, thinnest solder bridge I'd ever seen between the right most pin and the one next to it. I first thought it was just a bit of flux catching the light from my scope but i cleared it out anyways and voila. Everything was right as rain again. Anyways, thanks again for responding, and thank you for these videos. Thanks to you I'm feeling confident for whenever I do need to replace the encoder IC :)

Excellent! Congratulations on the successful repair :-)

It came directly from Amscope and amscope.com

+Darry Maggz They also use an MN864729A encoder.

thanks bro

The likelihood is that it won't do anything but it's always worth checking prior to confirming replacement.

I have a slender ps4 that does not give an image after a high voltage, I will try to make a reflux to the chip ic panasonic

+ABDEL GHAFFÂR hi, I don't think anything other than replacement after that sort of damage will suffice. Check EMI filters also as it's likely they will be damaged too.

I'm in Bradford, W. Yorks.

Indeed. Sometimes if you have a dry-joint beneath the IC it can 'go' again shortly after - even working fine working for a few days beforehand. Give it a good reflow and see if it comes back to life - if not and the IC itself is damaged again then I'll more-or-less guarantee this is something in the users' setup damaging the IC. Often in these scenarios it's either a faulty HDMI cable or the user is running the PS4 through a cheap HDMI switch or converter (i.e. HDMI to DVI etc). I also find some cheap off-brand TV sets can be more prone to damaging the IC than a 'branded' set.

That´s what i thought as he told me the first time he switched TV´s from his to his Girlfriends model and after that the thing was gone... Well i´ll see what happened there when it arrives here and want to thank you once more for taking the time to give me your "thoughts" about this. Take Care Mate wish you a great weekend ;-)

Cheers bud.

No, it's an 8.4mm diameter tip. That is the middle of the three provided sizes. The tip in use on this video is an add-on nozzle (it's kinked to allow use under the 'scope) - part No. M207.

+Alberto Padilla you'll either need a measurement from a known good board or take the component from a donor board without schematics.

There are no schematics? Could you measure an older model of ps4? Thanks again

Depends really - you'd be best measuring like for like but as a general rule SAA/SAB boards are going to be largely similar, SAC will need comparing with SAC and SAD with SAD.

Andrew Paul Could you get me the data I need? I'm looking for information for all the sites and I do not find anything, if I have to pay you money I'll pay you, thank you

Which board / resistor are you missing? Have any pictures of the location of the component you're missing?

Hi, Yes all 12xx based consoles use the MN864729 encoder.

Andrew Paul okay thanks :)

Hi, Feel free to drop me a message at ytandrewpaul@outlook.com. Cheers.

Andrew Paul hi mate I have

Could be a bad antenna, loose connection into the BNC connector or a physically faulty BT/WiFi module.

Andrew Paul alright thx m8!
